Helpful demonstrations of 'less than'

Identifying rocks

We have been investigating different rocks by using clue cards to help us. We made close observations of each rock and also made drawings to help us.

Permeabilty

We have then moved on this week to check the rocks using a specific test criteria to help us: To find out which was the best rock for Stig to use as a sink. The rock needed to be hard enough to cope with all the washing up and impermeable, so that it wouldn't let water soak in. Following our investigation, we decided that either Granite or Marble would be the best for this job.

Volcano eruption

Linked to our topic, we have been looking at different volcanoes and what causes them to erupt. Using a combination of vinegar and bicarbonate of soda, we were able to create a small eruption from our volcano. We spoke about the pressure building up in the Magma chamber, forcing magma up the Conduit and then the Throat of the volcano. Our mixture erupted through the vent and our lava then flowed down the sides of the volcano.
